Question

Find out the Multiplicative inverse of 7 and 11 in Z13* and also find out


the relatively primes from this set.​

Answer 1

Answer:

Explanation:

The multiplicative group of invertible elements in Zn is called Zn*. ... When you use the Euclidean algorithm to determine whether a and n are relatively prime, the algorithm ... If we compute gcd(17,8), we find ourselves doing the following: ... is the inverse of 7 mod 11. We start out computing gcd(11,7):. 11=1*7 + 4. 7=1*4 + 3.
